Spring Steel Wire
Spring steel wire is a kind of steel wire used to make springs (SPRING) or wire forms (WIRE FORM). According to the different uses of springs, there are many types of spring steel wires required for making springs, such as spring steel wires for mattress springs (referred to as mattress steel wires), spring steel wires for shock absorbers, and springs for suspension springs. Steel wires, spring steel wires for engine valves, spring steel wires for camera shutters, etc. Although there is no unified standard classification name, the quality requirements of these steel wires are different. Spring steel wire can also be classified according to the manufacturing process, such as raw drawn spring steel wire (without lead bath quenching before drawing), lead quenched spring steel wire, galvanized spring steel wire, oil quenched spring steel wire, etc.

#45-80 Chemical composition
65MN Chemical composition
The difference between 65MN and #65: The content of MN, the content of manganese has hardenability. After 830 degree heat treatment, the wire cools quickly, making it wear resistant


1) Strong corrosion resistance: It has excellent corrosion resistance, can be used for a long time, withstands harsh environmental conditions, and is suitable for various corrosive conditions.

2) High strength: It has high strength, as well as excellent tensile strength and compressive strength, which can meet the requirements of different applications.

3) Good wear resistance: it has wear resistance, can resist high temperature, high pressure and harsh environmental conditions, and can be used for a long time.

4) Low modulus: It has a low modulus, which can improve the overall rigidity and meet the quality and stability required for installation.

5) Reliable quality: It has the characteristics of reliable quality, which can meet different installation requirements and improve the service life of the product.
